Which automaker co-developed ISOFIX with Britax-Römer?

Volkswagen co-developed ISOFIX with Britax-Römer.

The partnership joined a vehicle manufacturer with a child-safety-seat specialist to create a standardized way to attach a child restraint directly to a car. Instead of relying only on the vehicle’s seat belt, ISOFIX uses rigid attachment points built into the vehicle and matching connectors on the child seat. The first compatible products were released in 1997.

ISOFIX was subsequently formalized through the international standard ISO 13216. Its basic arrangement uses two lower attachment points, with a top tether or another approved anti-rotation method depending on the seat and vehicle configuration. The system was intended to reduce installation errors and make child seats easier to fit consistently.

A common mix-up is treating ISOFIX as a Volkswagen-only technology or as the name of a single seat model. It is an anchorage standard. In the United States, a related system is commonly called LATCH, while ISOFIX is the familiar name in many other markets. The names and detailed regulations vary by region, but the core goal is the same: secure child restraints to dedicated vehicle anchorages.
